Read --utube actually-- today of man with highly educational degrees and on top of that list a neurosurgen also, and that man stayed on one year with Musk Neural Link, then thought this was too intrusive to the brain.
Then he went on to develop less intrusive { think patch } that slips between skull and top of brain, so less centimeters** into the brain as neural links are 4 - and 8 centimeters planned{ ? }**, and all knew this intrusive vertical links into brain, vis the animal experiments, these link-sticks retract over time.
That doesnt sound good. Retract to whwere exactly? The brain linning? The skull?
And his these alternative, thin sensor wafers, are used mainly on people who already have some disease of the brain, and **these sensors are better at getting data** from those people with disease than the the more intrusive neural links.
The analogy he uses is this, imagin as if your in your appartment listening to muffle sounds, through wall, in appartment next door. With his systems, you at their apt. door, and your open the door and and gather data from the doorway, whereas with neural links, your intruding into the crowd of people { the brain cells/matter } to get data.
Sorry I dont have the link any more. Again this dude has so many tech skills under his belt, and being a neurosurgon was just icing on his educational list. His surgies also so much less intrusive to scalp and skull as well as brain, than the neural links.
